Abstract
A technique for characterising fingerprints includes generating autocorrelation patterns of an image of a fingerprint in order to produce data indicative of these patterns. The data so produced is utilised for statistical comparison with stored data so as to determine whether the image of the fingerprint under test is derived from the fingerprint represented by the stored data. <IMAGE>
